title: [Allergic skin reaction in cattle to inactivated adenovirus allergens].
abstract: Comparative investigations were carried out of the skin allergic reaction in cattle infected with adenoviruses, using purified proteins and unpurified homologous allergens. All calves and cows that responded positively in the skin allergic test were shown to yield equal results, i.e. the allergic response with the use of the first type allergens coincided with that obtained with the other type, however, at the site of injecting the semipurified allergens the reaction was more strongly expressed. At visual reading the edema was well limited, projecting and better seen. There were certain age-associated differences in the developmental dynamics of the skin allergic reaction. The more advanced the age of cattle the higher the specific supersensitivity. On the base of results obtained in comparative investigations with a view to practically employing the test it is suggested to use semipurified adenoviral allergens.
